How to save your Iphone battery and make it last longer

Wireless 

Wireless connectivity will drawn your battery even if you are not using it. Keeping it on, it will always try to connect to some open hot spot, try to check your emails and much more. So a good idea is to turn it on when using, and after, turn it off.

Bluetooth 

Bluetooth have a similar battery usage as Wi-Fi, so there’s not much reason to leave it on if you are not using it (I believe that the most common usage for bluetooth today is the headsets and car kits).

Auto-Brightness

Auto-brightness is a interesting thing apple made to make the battery last longer. It uses iphone’s camera to adjust brightness based on the lighting conditions outside, so it will automatically set, for example, to make it less bright when you are on a dark place.

Music EQ

Music EQ will have a significant battery usage if you listen to your songs for many hours everyday, as it uses more processing power. So if you want to charge less your iphone, it is another thing you may consider turning it off.

Heat

Heat can be a problem to your iphone, as it is a very bad thing to lithium-ion batteries, making them harder to charge and destroying it due the intense ionization. So remember to never let your phone in a hot place such as inside a car or in direct sunlight. If you are using some kind of carrying case, you need to be even more careful about this, and remember to take it off when charging your mobile, as it gets warm when charging.

Keep it charging

After putting your phone to charge, leave it there for some hours more after it says it’s full. It will make your phone battery last much more, you will be surprised! After done that, my iphone battery lasted more then a week, way more if you compare to the 2-3 days when I was disconnecting if from the dock just after it says its full.

Background Programs

This is important, new iphones, such as Iphone 3GS above allows you to run multiple application on the background, but this will drain your battery fast if you forget to close them. To do this, double click on the round button and it will show all the apps currently running, keep clicking in one of the applications and a red “X” will apear, then you can close all apps.
